The present invention discloses an amino acid complex and its application for reducing nitrate content in vegetable. Said complex composition is formed from (by weight portion) 0-100 portions of lysnie, 0-100 portions of methionine, 0-100 portions of arginine and 0-100 portions of proline, in which the content of at least one amino acid is not zero. Besides, said amino acid complex alao has the effect for promoting plant growth and raising vegetable quality.
Description
Technical field
The present invention relates to a kind of amino acid coordination compound that reduces Nitrate in Vegetable.The invention still further relates to the new purposes of this amino acid coordination compound.
Background technology
Excess ingestion nitrate (NO
3-And NO
2-General name) be one of inducible factor of disease such as human cancer, the contained nitrate of vegetables is the important source of the human nitrate that is absorbed.Nitrate salts content of vegetable reaches as high as 10000 milligrams of/kilogram fresh weights according to the study, even be the vegetables of results object with the gonosome, as beans and melon, also can reach 500 milligrams/kilogram more than the fresh weight.
For addressing the above problem, the technological approaches that adopts has at present: (1) balance fertilizing measure, studies show that in a large number nitrogenous fertilizer and potassium fertilizer application can reduce the vegetable nitrate accumulation, and use chloride fertilizer certain effect also to be arranged to reducing vegetable nitrate; (2) restriction is used and is contained nitric nitrogen fertilizer; (3) seek the material with the formation of inhibition nitrate, as Dyhard RU 100, but this material easily produces inhibition to plant growth, and environment is had certain toxicity.Therefore, need research and screening to have the novel substance that reduces nitrate salts content of vegetable.
Summary of the invention
The objective of the invention is to shortcoming, a kind of amino acid coordination compound that reduces Nitrate in Vegetable is provided at the prior art existence.Its mechanism of action is the activity that improves the key enzyme-nitrate reductase of vegetable nitrate conversion, thereby reduces the accumulation of vegetable nitrate.Adopt amino acid coordination compound of the present invention also to have the growth of promotion, improve the effect of quality of agricultural product and resistance, and nontoxic to crop.Be to reduce nitrate salts content of vegetable comparatively convenient and safe method and technology at present.
Another object of the present invention is this amino acid coordination compound to be used for reducing the nitrate content of vegetables.
For achieving the above object, the present invention has taked following technical scheme:
A kind of amino acid coordination compound comprises the component of following weight part:
Methionin 0～100
Methionine(Met) 0～100
Arginine 0～100
Proline(Pro) 0～100;
Wherein having a kind of components contents at least is not 0.
A kind of preferred as technique scheme, amino acid coordination compound is made up of the component of following weight part:
Methionin 20～75
Methionine(Met) 10～%0
Arginine 10～40
Proline(Pro) 5～40.
Amino acid composition in the described amino acid coordination compound, can be fermentation back purify or proteolysis after purify or the products of amino acid of chemosynthesis, can be L type, D type or DL type isomer, also can be above-mentioned amino acid whose salt.When preparing, convert, draw the add-on of a kind of amino acid salts or 2-4 seed amino acid salt by equivalent with amino acid whose salt.
Described amino acid coordination compound can be used for producing the product that reduces Nitrate in Vegetable, can be liquid foliage fertilizer, also can be solid fertilizer.
Compared with the prior art, the present invention has following beneficial effect:
Amino acid composition in the amino acid coordination compound of the present invention and proportioning are determined by a large amount of pot experiment screenings, show that using one matter that nitrate salts content of vegetable is reduced reaches 12～45%, uses compound that nitrate is reduced and reaches 21～65%.Field experiment shows, uses the probability that vegetable nitrate reduces more than 10% behind above-mentioned substance or the title complex and reaches 90%.
Single or the compound of the reduction vegetable nitrate that the present invention relates to, can be mixed with liquid foliage fertilizer, its compound method is that single amino acid or amino acid compound add 5 parts of water for 1 part, be heated to 80 ℃, and regulate pH to 3～5 with phosphoric acid and be made into clear liquid, spray or drench by the concentration of amino acid/11 00-500 mg/kg and execute, also can be made into and spray, drench and execute after solid fertilizer is converted water, or together use with chemical fertilizer.The application effect test shows: use above-mentioned amino acid or compound and have the growth of promotion, improve the yield and quality, strengthen the effect of crop anti-adversity.
Embodiment
The invention will be further described below in conjunction with specific embodiment.In following examples, represent to use the effect that reduces vegetable nitrate behind amino acid or the compound with nitrate reduced rate (%), with nitrate reductase (NO
2Microgram/30 minute gram fresh weight) represents the ability that nitrate transforms, nitrate reduced rate and nitrate reductase activity are high more, then show and use amino acid or title complex to have the function that reduces nitrate strong more, and adopt stimulation ratio (%), soluble sugar (% fresh weight), expression to use behind amino acid or the title complex effect for yield and quality.
The preparation method of amino acid coordination compound is as described in the summary of the invention part.
